Short answer
Cast-and-demold plan
Gel, demold and full cure are separate days
- Mix the Flexible 55A resin for LCD printers to ratio and pour
- Wait for the demold time
- Sand or finish after full cure
This product’s stated stages Quoted at 73°F
- Curing period10–15 minutes
Worth noticing: The manufacturer states only one timing here (curing period, 10–15 minutes); nothing else is inferred.
Common mistake: Demolding early and leaving a soft, tacky casting that never fully hardens.
Project stage ladder
Demolding, handling, finishing and final use may occur at different times
For 3D printing, flexible parts, and gaskets, identify which stage the stated period 10–15 minutes milestone actually unlocks. Earlier handling does not prove final cure.

About this product
A soft rubber-like resin cured 10 to 15 minutes under UV, rotating the part every 5 minutes. A heat treatment at 50°C comes before the UV step.
Using this specific product
Siraya Tech Rebound 55A Black is listed here as the Flexible 55A resin for LCD printers version for 3D printing, flexible parts, and gaskets. For casting resin, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.
Before you start
- Confirm the package says Flexible 55A resin for LCD printers; related versions can use different timing.
- For 3D printing, flexible parts, and gaskets, pay particular attention to accurate mixing, mold material, mass and room temperature.
- The source gives no conditions for this time.
How to check readiness
Check the casting itself for flex or tack before demolding. The data sheet says to cure with 395 to 405 nm UV light for about 10 to 15 minutes.
Avoid this mistake
Demold time is not necessarily full mechanical cure.
